Abstract

Disclosed is an anti-drop system of a construction elevator. The anti-drop system comprises one or more rope grasping devices and one ore more safety ropes, the rope grasping devices are mounted on a cage of the construction elevator, one end of each safety rope is connected on a ground floor or intermediate floor of a building, each safety rope extends upwards, changes direction through a rotary plate, a rotating wheel, a roller or a steel bar to extend downwards to penetrate the corresponding rope grasping device arranged on the cage and is fixed at an appropriate position below the cage, and the cage can grasp and fix the safety ropes through the rope grasping devices and suspends in the air, or the cage can grasp and fix slow descending ropes through the rope grasping devices so as to descend at a safety speed.

Description

technical field [0001] The invention belongs to the technical field of anti-falling of construction elevators. Background technique [0002] Construction elevator refers to the elevator used for vertical transportation in building construction to carry people and materials. It is also called external elevator because it is often attached to the outside of the building. In recent years, the use of elevators in high-rise buildings has become more and more common. However, due to the gap between product safety performance and general manned elevators, the working environment at the construction site is poor, the safety management of the construction unit is not in place, and the safety supervision ability of the supervision unit is insufficient. As a result, there are often major security risks in the equipment. For the construction elevator, it is the only vertical transportation equipment that can carry people on the construction site. Improper safety management is likely to...
